I just recently installed Star Trek New Worlds on laptop that has vista, and guess what? It works! Pax said that it was released for windows 95/98, but it works on vista. So if your having trouble loading Star Trek New Worlds on xp or any other operating system, then try vista!
Have you yet tried the compatibility tab under properties of the link? Set it to Windows 95. I told the Overseer of Vault 13 I'd give everything to save everyone, and so I did, I saved them all. Since then I've felt loneliness.
